Definitions

  • Unpolarized light irradiated from the backlight 80 is incident on the liquid crystal cell 65 in a linearly polarized light state via the mirror assembly 70 and the second polarizer 67, and on/off states are controlled based on a voltage applied to the liquid crystal cell 65 to form images. Disclosure of Invention Technical Problem
  • a reflecting member may be positioned at a rear surface of the backlight, and the reflecting member may reflect light that is reflected from the active reflective polarizer back to the active reflective polarizer.
  • a recycle member may be disposed on the reflecting member, and the recycle member may recycle light reflected from the active reflective polarizer.
  • the incident light of the first polarization is reflect ed towards the liquid crystal panel 300, and the reflected light is transmitted through the first polarizer 310.
  • the light transmitted through the first polarizer 310 is transmitted through the liquid crystal layer 350, it is converted to light of the second polarization. Accordingly, the light of the second polarization is transmitted through the second polarizer 390 to realize a pixel on-state.
  • Korean Patent Application No. 2007-0046199 of the present applicant Referring to the '199 application, as the thickness of the magnetic material layer 210 increases, the polarization extinction ratio increases. In addition, when the thickness of the magnetic material layer 210 is small, the polarization separation properties are excellent.

Abstract

L'invention concerne un dispositif d'affichage à cristaux liquides (LCD) pouvant être commuté entre un mode transmissif et un mode réfléchissant. Le dispositif LCD comprend un rétro-éclairage; un polariseur réfléchissant actif qui fonctionne comme réflecteur qui réfléchit une lumière incidente ou comme un polariseur réfléchissant qui réfléchit la lumière d'une première polarisation et transmet la lumière d'une seconde polarisation perpendiculaire à la première en fonction de l'application d'un champ magnétique; et un panneau à cristaux liquides qui module la lumière incidente pour former des images. Le panneau à cristaux liquides comprend une couche de cristaux liquides, un premier polariseur disposé sur une surface arrière de la couche de cristaux liquides et opposé au polariseur réfléchissant actif, et un second polariseur disposé sur une surface avant de la couche de cristaux liquides.
